MATTRESS-FRAME.

SPECIFICATION forming part of Letters Patent No. 510,541, dated December12, 1893. Application filed `Sejptenlber 20, 1893. Serial No. 485,964.(No model.)

` ication, like letters and igures on the drawings representing likeparts.

This invention has for its object to construct a metallic mattress frameespecially designed for woven wire or kindred mattresses, and consistsin many details of construction to be hereinafter pointed out.

Figure 1, shows in plan view a mattress frame embodying this invention,supporting a woven wire mattress; Fig. 2, an enlarged sectional detailof one of the corners taken on the dotted line x, Fig. 1; Fig. 3, anenlarged sectional detail of another corner taken on the dotted line y,Fig. 1 Fig. 4, a cross section of one ot' the end rails with themattress removed; Fig. 5, a similar cross section of one 0f the endrails with the mattress engaged and held by it; Fig. 6, a perspectiveview of one of the corner blocks which are placed between the side and'end rails.

The side rails a., b, are made alike consisting of cylindrical tubularmetallic rods or bars, and the end rails c, d, are also made alikeconsisting of cylindrical tubular metallic rods or bars, slitted as atc', see Fig. 4, from end to end. The side rails and end rails arearranged at right angles with relation to each other to form aquadrangular frame, and t0 prevent said rails twisting or turning onewith relation to another when secured together, blocks e, see Fig. 6,are interposed between the side and end rails at the corners where saidrails cross one another, said blocks having each two grooves formed init, one upon its upper and the other upon its under side, and arrangedat right angles with relation to each other, and shaped to kreceive theside and end rails. At one corner of the mattress frame, a bolt c2,passes down through holes made in the end rail c, also through a holemade in the interposed block e, and through slots a made in the siderail a, said bolt being supplied with a nut c3. This bolt c2, securesone end of the end rail c to one end of b, adjacent the end rail c, areclosed by caps c4 having externally projecting squared ends c5 adaptedto receive a wrench, and having -screw threaded holes through them whichreceive the Shanks of the eye-bolts c6, the eyes of which embrace or areconnected with the shanks of the bolts c2. Said closing caps thereforeserve as nuts and by turning them in one or the other direction, thebolts czwill be correspondingly moved in the slots in the side rails,thereby adjusting the end rail c with relation to the end rail d. Thinmetallic plates f are or may be placed upon each side of the side railsto cover the slots a therein. At the opposite end ofthe mattress framethe end rail d is embraced at points near the ends by straps d', theends of which pass down through the side rails a, b, see Fig. 3, and aresupplied with nuts cl2, thereby firmly securing the said end rail withthe block e interposed between it and the side rails. The strap d', itwill be seen, may be loosened and thereby permit the end rail d to beturned by means of a Spanner or wrench, to tighten the mattress ifdesired, after which said strap may be tightened, or in lieu ofadjusting the mattress at this end of the frame in this manner, it maybe adjusted similarly to the opposite end of the frame.

When a Spanner is used for turning the end rail d it may be made toengage the head of a short bolt 2, as represented by dotted lines Fig.5.

In securing the mattress tothe end rails c, d, the ends of the mattressare inserted in the slots c', and short bolts 2, pass through said 4endrails supplied with nuts 3, so that by turning said nuts the end railsare contracted thereby firmly clamping and holding the ends of themattress. The short bolts 2 may and preferably will pass through themeshes of the mattress as represented' in Fig. 5.

1. The mattress frame herein described consisting of the combination ofthe cylindrical tubular side rails a, b, and the cylindrical tubular endrails c, d, and interposed grooved blocks e, made as shown, and bolts orequiva- IOO lent fastenings securing said side and end rails together.

2. The mattress trarne herein described consisting of the combination ofthe side rails ct, b, slotted at the ends as at a', the end rails c, d,and interposed grooved blocks e as shown means for securing the end raild to the side rails, and the bolts c2, for securing the end rail c tothe side rails, movable in the slots ct thereof, nuts c4 and eye-boltsc6 engaging the bolts c2, substantially as described.

3. In a mattress frame, the combination of side rails ct b, and endrails c, d, one of which is slotted from end to end to receive the endof the mattress, and short bolts 2, passing through said slotted endrail and nuts 3, which When tightened contract the slotted end rail andthereby firmly clamp and hold the end of the mattress, substantially asdescribed.

4. ln a mattress frame, the combination of side rails a, b, and endrails c, d, one of which is slotted from end to end to receive the endof the mattress, and short bolts 2, passing through said slotted endrail and nuts 3, Which when tightened contract the slotted end rail andfirmly clamp and hold the end ofthe mattress, and straps d embracingsaid end rail, the ends of which are connected with the side rails,whereby said end rail may be rotated when said straps are loosened,substantially as described.

In testimony whereof We have signed our names to this specication in thepresence of two subscribing Witnesses.
